ENCORE DDS Guide - Developer Reference Non-Proprietary Transmissions

ENCORE – Data Distribution Services Guide Developer Reference I Non-Proprietary Transmissions

Version 3.15 Sept. 2017

© 2017 The Options Clearing Corporation. All rights reserved. Reasonable measures are taken by OCC to ensure the accuracy of the information it distributes in its DDS program. This information is produced from data received from a number of different sources, which are believed to be reliable. However, due to the number of sources for such data, the possibility of human error, and the risks inherent in electronic distribution, there may be omissions or inaccuracies in such information and delays or interruptions in providing it. Accordingly, OCC disclaims all express or implied warranties with respect to the information distributed in its DDS program, including any warranty of merchantability or fitness for a particular purpose. Further, information sent on a real time basis should not be considered final until OCC issues an end of day message advising no additional transmissions will be made on a particular business day.

To read DDS FIXML messages, OCC recommends using an XML parser that adheres to the W3C* 1.0 and 1.1 XML recommendations and not the byte by byte method typically used for “flat file” parsing. In order to support new future business needs, OCC reserves the right to add at any time previously unused tags, which are already part of the FIXML schema, to the DDS FIXML messages. If the parsing mechanism recommended above will be used, the addition of new tags will have no impact on the programs that read in the DDS FIXML messages.

For the following cases: - addition of new tags which are not part of the FIXML schema - addition of new enumerations which are not part of the FIXML schema - addition of previously unused enumerations which are part of the FIXML schema - decommission/removal of existing required tags

OCC will notify designated contacts in advance of their implementation. When needed, updated schemas will be made available, in advance, on OCC's website.

OCC — Last Updated Sept. 2017 ENCORE Data Distribution Services Guide – Non-Proprietary Transmissions — Version 3.15 — Page 5 Document Organization This document is one of a set of three intended to provide a detailed description of all aspects of the Data Distribution Services system: Part One: Data Distribution Services Overview. This section is intended for a reader that needs to understand the Data Distribution Services (DDS) system. This part of the guide contains the design concepts and the data delivery services being developed and implemented. Part Two: Developer Reference – Non-Proprietary Transmissions. This section is intended for use as a Non-Proprietary Transmission mapping reference for FIXML developers. This part of the guide includes FIXML elements, transmission layouts, message structures, and sample messages for each transmission. Part Three: Developer Reference – Proprietary Transmissions. This section is intended for use as a Proprietary Transmission mapping reference for FIXML developers. This part of the guide includes FIXML elements, transmission layouts, message structures, and sample messages for each transmission.

Glossary of Terms You should be familiar with the following terms prior to reading this guide. Batch – In a computer, a batch job is a program that is assigned to the computer to run without further user interaction. In larger commercial computers or servers, batch jobs are usually initiated by a system user. Some are defined to run automatically at a certain time. DDS (Data Distribution Services) – The ENCORE module that supports both batch and real- time data delivery and utilizes the FIXML data formatting standard. ENCORE – The clearing system utilized within OCC. Event Driven Processing – A business event is a meaningful change in the state of the enterprise, such as the opening of a new customer account, clearing a trade, or the matching of a transfer. Event driven processing is system behavior that is initiated by these business events rather than system events—such as time based scheduling. Event driven systems possess the following attributes: 1) Individual treatment of transactions; 2) Push delivery systems; and 3) Electronic notification. FIXML (Financial Information eXchange Markup Language) – The XML derived grammar of the FIX protocol. A FIXML implementation will have message format validation, cleaner, more expressive structure, and leverage off existing standards. The initial goal is to provide the ability to embed FIXML messages within traditional FIX header and trailers to minimize the impact on existing implementations. Messaging – There are two major messaging server models: the point-to-point model and the publish/subscribe model. Messaging allows programs to share common message-handling code, to isolate resources and interdependencies, and to easily handle an increase in message volume. Messaging also makes it easier for programs to communicate across different programming environments (languages, compilers, and operating systems) since the only thing that each environment needs to understand is the common messaging format and protocol. Package – A Package is a collection of DDS transmissions that are grouped together based on selections made when the subscription was created.

OCC — Last Updated Sept. 2017 ENCORE Data Distribution Services Guide – Non-Proprietary Transmissions — Version 3.15 — Page 6 Pull Delivery Model – In this information delivery model, the observer—or client—requests information from the information owner. An example of this model is the download of a document from a web page. Push Delivery Model – In this information delivery model, the information owner distributes the data to the observer as it deems appropriate. An example of this model is the sending and delivery of an email message. Real-Time – A level of computer responsiveness that a user senses as sufficiently immediate or that enables the computer to keep up with some external process (for example, to present trade data as trades are executed and cleared). Real-time is an adjective pertaining to computers or processes that operate in real time. Real time describes a human rather than a machine sense of time. Recipient – The entity (Clearing Member Organization, Exchange, Regulatory Agency or Service Bureau) that owns the systems where DDS delivers data for processing or retransmission. STP (Straight-Through-Processing) – The seamless integration of systems and processes to automate the trade process from end-to-end--trade execution, confirmation and settlement-- without the need for manual intervention or the re-keying of data. Subscriber – The entity (a Clearing Member Organization, Exchange, or Regulatory Agency) that requests a package of transmissions and owns the data that is transmitted to recipients. XML (eXtensible Markup Language) – A simple and flexible text format derived from SGML (ISO 8879). Originally designed to meet the challenges of large-scale electronic publishing, XML is also playing an increasingly important role in the exchange of a wide variety of data on the Web and elsewhere. Special purpose XML languages and standards are commonly developed with several hundred already adopted since XML 1.0 was released in February 1998.

OCC — Last Updated Sept. 2017 ENCORE Data Distribution Services Guide – Non-Proprietary Transmissions — Version 3.15 — Page 7 Transmissions This section provides the FIXML elements, transmission layouts, message structures, and sample messages. The Non-Proprietary ENCORE transmissions below are defined on the following pages:

OCC — Last Updated Sept. 2017 ENCORE Data Distribution Services Guide – Non-Proprietary Transmissions — Version 3.15 — Page 8 CFI Code Default Values In an effort to reduce the size of the document, the standard mapping and data values for the CFI Code tag is presented below and not repeated throughout the document. Only in situations where the CFI Code values will differ from the default values below will the CFI Code be detailed in the document.

OCC has tried to provide as much product information as possible through the CFI Code. However, since this field is part of an ISO standard, OCC had to limit the amount of information provided to the confines of the standard.

OPTIONS CHAR1 = O CHAR2 = Put/Call Code CHAR3 = Exercise Style Code (A = AMERICAN, E = EUROPEAN) CHAR4 = Classification (S = EQUITY, I = INDEX, O = OPTION, F= FUTURE, D = DEBT) CHAR5 = Settlement Method (P = PHYSICAL, C = CASH) CHAR6 = Sub-Classification Standard / Non-Standard Settlement Designation (S = STD SETTLEMENT or N = NON-STD SETTLEMENT)

WARRANTS CHAR1 = R CHAR2 = W CHAR3 = X CHAR4 = X CHAR5 = Put/Call Code CHAR6 = X

FUTURES CHAR1 = F CHAR2 = F CHAR3 = Classification (S = EQUITY, D = DEBT, I = INDEX) CHAR4 = Settlement Method (P = PHYSICAL, C = CASH) CHAR5 = Standard / Non-Standard Settlement Designation (S = STD SETTLEMENT or N = NON-STD SETTLEMENT) CHAR6 = X

NOTE: As evidenced above, when a particular CFI Code attribute does not apply to the use or context within a message then an X will be used.

OCC — Last Updated Sept. 2017 ENCORE Data Distribution Services Guide – Non-Proprietary Transmissions — Version 3.15 — Page 10 ENCORE Transmission: Market Data Full – Open Interest

FIX Message: Market Data Snapshot Full Refresh Report Subscription Options: Commodity Options Equity/Index Options Futures Delivery Options: Batch File

Overview Open Interest information is available on the Market Data Snapshot Full Refresh (Market Data Full) Report. For each active option series or futures contract, one message is created indicating the open interest quantity. Open Interest is calculated as the quantity of open long positions for a given contract or series. If the contract or series has an open interest quantity of 0 (no positions), the process still creates an Open Interest message.

The Full Product transmission includes option or future product information such as the symbol, assignment method, exercise style, classification, position limit, near term limit, trade source listings, CUSIP, and allocation percentage. One message is created for each active or pending active product. It reflects any updates that may have been made during the day and is a snapshot of OCC’s product database at the end of the business day.

FIX Message: Security Definition Update Security List Update Subscription Options: Options Commodity Options Futures Delivery Options: Batch Real Time

Overview The Security Definition Update Report includes all updates made to an option or future product such as symbol changes, position limit changes, trade source listing changes, or underlying deliverable changes. The Security List Update Report includes all updates made to an option series or future contract such as new series, deleted series, strike price changes, or ticker symbol changes. In both of these reports, the Instrument block includes updated information to the product or series. In determining how to process the block, the user must look at the Status. The updates are processed as follows:

- If the action is ADD, then there is one Instrument block listing the new product/series. - If the action is MODIFY, then there are two Instrument blocks: one block listing the pre-change product/series and one block listing the updated product/series. - If the action is DELETE, then there is one Instrument block listing the deleted product/series. If a Clearing Member subscribes to the updates, they receive both the Security Definition Update Report and the Security List Update Report. Both product and series/contract information are included in one transmission.

Corporate Action Processing

Products A Security Definition Update message with an Update Action of Add is generated for the new product. This message includes a single Instrument block with a status of Active. No notification is made of the adjusted product since OCC will continue to maintain the product as active for an undetermined amount of time due to possible processing issues. If the product is made inactive at some later date, the inactivation will be sent to DDS subscribers at that time but the relationship to the corporate action will not be communicated.

Series/Contracts A Security List Update message with an Update Action of Modify is generated to show the modification of the Inactivate Date on the old series or contract. This message includes two Instrument blocks: one with a status of 2 (Old) and another with a status of 1 (New).

A Security List Update message with an Update Action of Add is generated for the new series or contract. This message includes a single Instrument block with a status of 1 (New).

A Security List Update message with an Update Action of Modify and the appropriate Corporate Action code is generated to show the relationship between the newly activated instrument and the newly inactivated instrument. his message includes two Instrument blocks: one with a status of 2 (Old) and another with a status of 1 (New).

On deletes and modifies with status = 2, database lookups are not performed for certain fields. The specific series info (product symbol, CFI Code, expiration date, strike, and activation date) should be used as a key for lookup on the DDS users systems.

OCC — Last Updated Sept. 2017 ENCORE Data Distribution Services Guide – Non-Proprietary Transmissions — Version 3.15 — Page 96 Corporate Actions

Corporate Action Codes DDS Corporate Action field values are:

DDS Corporate Action Type (FIX Enumeration) Cash Dividend F Stock Dividend G Non-Integer Stock Split H Reverse Stock Split I Standard-Integer Stock Split J Position Consolidation K Liquidation Reorganization L Merger Reorganization M Rights Offering N Shareholder Meeting O Spinoff P Tender Offer Q Warrant R Special Action S Symbol Conversion T CUSIP / Name U Position Consolidation Symbol Conversion K T Wrap Not Applicable

OCC — Last Updated Sept. 2017 ENCORE Data Distribution Services Guide – Non-Proprietary Transmissions — Version 3.15 — Page 97 In addition to the changes to corporate action code indicators, additional considerations must be defined for Corporate Actions processing. Due to the way that a Corporate Action is processed in the ENCORE system, a CA adjustment that requires a new instrument to be listed by the OCC would create the following FIXML message flow: An example of the SecListUpd message flow resulting from a 2-for-1 Stock Split Corporate Action follows:

(1) Modify message reflecting the new Inactivate Date for the Series that is to be split.

(2) Add message reflecting the new Series (post-split).

OCC — Last Updated Sept. 2017 ENCORE Data Distribution Services Guide – Non-Proprietary Transmissions — Version 3.15 — Page 98 Uniqueness Checking The nature of real time messages creates the possibility of multiple messages per series update. Therefore, recipient systems must interrogate the following fields and check for uniqueness against previously processed security update messages for the current processing day.  RptID  BizDt  CorpActn (for Series/Contracts only)

Explanation of DDS Product Multipliers

With the implementation of ENCORE, several product multipliers were introduced to simplify the calculation of various derived/extended values used throughout OCC’s clearing system. Below is a breakdown and explanation of these multipliers in DDS.

Strike Multiplier (tag name StrkMult)

The strike multiplier is a number that identifies where the decimal for the strike price should be. For example, for a strike of $1,000, a multiplier of 0.1 will help tell us the actual strike. In this example it is $100.

The Strike Multiplier is always 1.0 for Equity Options, is usually 1.0 for Index Options, but will be 0.1 for “half-point” Index Options.

Strike Value (tag name StrkValu)

The Strike Value is a number that the user will define for 1 unit of strike value.

For example, if the strike value = 100, then a strike of $17 would equal to $1,700. This field will be used for calculating extended strike values and is used to make calculating extended strike and settlement value easier and more intuitive.

The number of units represented by the Strike Value is comprised of: 1) Number of shares for Equity Options 2) A dollar amount for Index Options

The typical value of this multiplier for Equity and Index options is 100.

The Strike Value in DDS accounts for products with multiple delivery components.

Trade Value (tag name Mult)

It is a number that the user will define for 1 unit of trade premium value. For example, if the trade value = 100, then a premium of $1.50 will be equal to $150. This field will be used for calculating premium money extensions.

The number of units represented by the Trade Value is comprised of: 1) Number of shares for Equity Options 2) A dollar amount for Index Options

The typical value of this multiplier for Equity and Index options is 100. In the majority of cases, the Trade Premium has to be extended to the same base as the Strike Price. Therefore, the Trade Value will usually be the same as the Strike Value.

OCC — Last Updated Sept. 2017 ENCORE Data Distribution Services Guide – Non-Proprietary Transmissions — Version 3.15 — Page 102 Use of Product Multipliers in Extended Value Calculations

Extended Strike Calculation

DDS method of calculating extended strike: extended strike price = strike price * strike multiplier * strike value

Extended Trade Premium Calculation DDS method of calculating extended premium: extended trade premium per contract = trade premium * trade value * no. of contracts

Various Product Examples

Standard Equity Option

Symbol = IBM Strike Price = $75 Trade Premium = $3.25 No. of contracts = 25

DDS: Strike Multiplier (StrkMult) = 1.0 Strike Value (StrkValu) = 100 Trade Value (Mult) = 100

Extended Strike Price (DDS) = strike price * strike multiplier * strike value = $75 * 1.0 * 100 = $7,500

Extended Trade Premium (DDS) = trade premium * trade value * no. of contracts = $3.25 * 100 * 25 = $8,125

OCC — Last Updated Sept. 2017 ENCORE Data Distribution Services Guide – Non-Proprietary Transmissions — Version 3.15 — Page 103 Equity Option After a 3 for 2 Stock Split

Symbol = YIW Strike Price = $35 Trade Premium = $2.75 No. of contracts = 25

Extended Trade Premium (DDS) = trade premium * trade value * no. of contracts = $2.75 * 150 * 25 = $10,312.50

Standard Index Option

Symbol = DJX Strike Price = $76 Trade Premium = $1.50 No. of contracts = 25

Extended Trade Premium (DDS) = trade premium * trade value * no. of contracts = $1.50 * 100 * 25 = $3,750

Mini Index Option

Symbol = QCE Strike Price = $125 Trade Premium = $1.50 No. of contracts = 25

Extended Trade Premium (DDS) = trade premium * trade value * no. of contracts = $1.50 * 10 * 25 = $375
